Abstract

La présente invention concerne de nouveaux ensembles d'électrodes à membrane, ainsi que des dispositifs et des systèmes les incorporant. Des ensembles représentatifs d'électrodes à membrane comprennent : (a) une première électrode poreuse; (b) une couche tampon comprenant éventuellement une solution aqueuse comprenant un tampon de pH; (c) une membrane; et (d) une seconde électrode poreuse comprenant un catalyseur pour la génération d'oxygène (02). La membrane est interposée entre la première électrode et la seconde électrode, et la couche tampon est interposée entre la membrane et la première électrode.
